Application filed February 3, 191-5. SeriaIN-o. 5,857.

To all, whomit "may; concern:

Be it known that LdVnNznI-J SCHEICK, a citizen; of the: United States, and resident of \Vaterbury, in the county of New Haven and, State of Connect-icunhave invented certain new and useful Improvements in Air- Injectors, of which the following is: a specification.

My invention relates to an improved form of air injecting apparatus and is designed especially for introducing a blast of cold air into beer vats, while cleaning and refinishing the same.

Vats or tanks employed: in the production of beer have to be scraped and revarnished upon the inside once or twice a year in order to keep them cleanand wholesome. Thus it IS necessary after drawing off the liquid" beverage to send one or two men into the tank, first to dry it out, then to scrape the inner walls and finally to shellac and varnish the same. The alcohol fumes from the shellac are very strong and frequently the men are overcome thereby unless suitable precautions are taken to prevent it.

I have therefore devised my present invention for the purpose of injecting fresh air into tanks of this sort while the men are at work therein and so that the inflowing air may be directed against and into the faces, if necessary, of the workmen, while engaged in the varnishing operation.

The object therefore of the invention is to provide a simple and practical form of portable injector which can be readily placed in front of a beer tank and put in operation and as easily shifted from one tank to another; to construct the injector so that but a small quantity of compressed air will be required, and may be used with a larger quantity of atmospheric air; further to employ a portable stand for supporting the device having adjustable connections whereby the tube can be raised and lowered or ad justed to line with the manhole in the tank and in a manner to provide for throwing the blast of air into any portion of the tank required.

With these and other objects in view the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion,

size and minor details of construction within the scope of the claim may be resorted to w thout departure from the splrit or sacrificing any of the advantages of the invention.

Similar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawings formingxa partof this specification and upon which- Figure 1 shows'an elevation of a beer tank with my improved injector arranged in front thereof and in position for operation. Fig; 2 is a larger side view of the injector with the tube in a different position and Fig. 8 is a transverse cross section of the injector and stand taken on line 33 of Fig. 2

Referring in detail to the characters of reference marked upon the drawings 5 represents the beer tank, 6 a vent pipe in the top of the tank, 7 an inlet and outlet pipe by means of which the liquid is run into and out of the vat. 8 is a cock in the supply pipe 7 by means of which the passage of the fluid therethrough is controlled.

9 represents a man hole in the front of the tank and through which the workmen enter the tank to clean and refinish the same.

The invention proper is more clearly shown in Fig. 2 and as will be noted comprises a portable stand including a heavy base 1.0 in which is secured a vertical upright 11. Upon this upright is mounted an adjustable bracket 12 that may be raised and lowered upon the upright and secured at various elevations by means of a set screw 13. This bracket is provided with an extension l l that is provided with a socket in which the shank 15 of a forked support 16 is seated. This support may be adjusted to various positions in the bracket and is secured by means of a set screw 17. The end portions of the two divisions of the support 16 are provided with holes 18 in which a supporting pipe 19 is secured. This pipe serves the double purpose of supporting the tube 20 and as a means of introducing air into the tube. The tube so called comprises a length of relatively large pipe the ends of which are open and which has an unobstructed air passage therethrough. The pipe extends crosswise through the center of the tube and is provided with a series of small I outlet holes 21 to admit the air into the tube that is arranged to swing pon it so that the perforated pipe 19 and to this valve is attached a flexible pipe 23 that in turn is connected with a compressed air supply, not" shown. It will thus be seen that when the valve is open and the compressed air supply turned in, the said inflow of compressed airwill serve to draw in the cold air from the atmosphere and carry it through the pipe and force it out from the discharge end 23. i v

This form of device insures a relatively larger volume of fresh air being supplied in the vat with the use of a comparatively small quantity of compressed air and further provides for the distribution of the air in any section of the tank by the assistance of an attendant on the outside in charge of the device and who merely adjusts the nozzle to the various positions required to send the air in such sections of the tank as may be desired.

Copies of this patent may be obtained 'for five cents each, by addressing the Commissioner of Patents,

Washington, D. 0. i

Having thus described my invention what I claim and desire to secure by Letters Patent is l An air injecting apparatus of the class described, the same comprising a stand including a base and upright, a bracket adjustably mounted thereon, a support adjustably mounted in the bracket and provided with outwardly disposed forks having holes in their end portions, a perforated pipe sup ported in the holes of the forks, atube piv-- otally mounted on the pipe and covering the perforations, a. valve connected to the pipe and a compressed air supply pipe connected with the valve to supply air to the perforated pipe and tube.
